To facilitate pressure-water supply into the system, the cabinet is equipped with two knock-out holes at the top and bottom of both side walls of the cabinet. Dimensions of hydrant cabinet made of 1 mm steel sheet – 800x800x340mm. Its surface is textured, coated with RAL 3000 (red) or RAL 9016 (white) tint powder for indoor applications.
